GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 266,284, dated October 24, 1882,

Application filed March 15, 1881.

To all whom it may concern:

Be it known that I, ALBERT GOODYEAR, of Akron, in the county of Summit and State of Ohio, have invented certain new and useful In'iprovements in Grain-Binding Machines; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanyingdrawings, which form a part of this specification.

My invention relates to improvements in grain-binders, and more especially to that portion of such machines whereby the extremities of the encircling band (it being of cord) are united by being twisted together, and subsequently so treated by mechanical means that the said ends cannot of themselves become separated.

The object of my invention is to provide means for securing the band around a bundle in such a manner that when released from the machine there will he no slack to be taken up by the expansion of the bundle.

My invention consists in the mechanical parts, combined and operated as more fully hereinafter described, and particularly setforth in the claims.

To enable others skilled in the art to make and use my invention, 1 will now proceed to describe the same with reference to the drawings forming a part of this specification, in which Figure 1 represents an elevation of the front or delivery side of a grain-binder with my improvements attached. Fig. 2 is an end View with a portion of the frame removed. Fig. 3 is a plan View of the same. Fig. at is a side view of the same, taken from the inner side. Fig. 5 is ahorizontal section taken on the line a- 00 of Fig.4.

()nly that part of a binder is shown in the drawings which is necessary to illustrate the operation of the device.

The cord used with my invention will be tarred.

In the drawings, A represents the binderframe which supports the parts composing the operative mechanism of my invention; B, the

(No model.)

binder-platform, whereon the grain is delivered to be bound; 0, the binder-arm, which has suitable guides and an eye at the end, through which the cord is passed; 0, a cord-reel placed in any convenient place.

Before com mencing the operation of binding the cord is threaded through the guides and eye of the arm 0 and the end secured in the, cutter and holder (1. As the grain is delivered onto the platform B the arm 0 descends, and the cord, yielding to the pressure of the grain, is laid around the bundle. The point of the arm 0 descends below the line of the platform B and the cutter and holder (1, thus delivering the cord to said holder and to the twister b. The cutter and holder severs it and secures the end of the main cord for the next bundle.

The cutting, holdin twisting, clamping, and tucking mechanisms, which embody the essential elements of my invention, are arranged on a frame, E, attached to the hinder-frame A,

either in a position like that shown in Fig. 1 or otherwise, as may be best suited for the work.

The cutter and holder at consists of a rotating toothed wheel, the teeth of which'radiate from a common center, and are hook-shaped, as shown in Fig. 5. It is mounted on a vertical shaft, a, to which motion is communicated from ahorizon al shaft, a having the hit'urcated earn a through intermediate gearing, Figs. 1 and 2. The cutter a runsbetween the. plates 0 e, in each of which is a slot, 0 as shown in Figs. at and 5. volves its teeth pass across the edge of these slots. Theedgeot' the upperplate, c,is sharp, similar to the edge of shears. By reason of the peculiar form of the teeth ot the cutter and holder at the cord isdrawn toward its axis when it revolves, for reasons hereinafterstated.

. The twister I), Fig. 5, also has radial hookshaped teeth, and it revolves around an axle, U, which is formed by a continuation of the cutter-shaft a. Motion is imparted to the twister Z) by the toothed wheels I) on the vertical shafts N, which are actuated from the shaft a through intermediate gearing. Motion is imparted to the shaft a from a segmental gear-wheel, A, which is caused to revolve by power suitably communicated from As the cutter a rethe drive-wheel of the harvest-er, and thus the parts are caused to operate in proper time and in unison.

Directly above the cutting, holding, and twisting wheels is located what I term a clamping and a tucking device. The clamp consists of a stationary arm, d, located and formed as shown, and an arm, (1, pivoted atf, formed as shown, and having the projecting lever-arm (P. .The movable arm (1 is operated by means of cams on the wheel g, through the lever-arm g, with which itis connected by the rod 9 A spring, 1', serves to retract into its normal position the lever g, after having been operated by the cams on wheel 9. The tucker It, located and formed as shown, is attached to the extremity of a short shaft, or, which is journaled in the bearings n, and has the spur-wheel k keyed to its other end. An intermittent rotary motion is imparted to the tucker k by means of a segmental rack on the upper extremity of the lever 9, which lever is pivoted at m, the teeth of the rack meshing with those of the spurwheel 7.:, as shown.

The peculiarities and merits of my invention will be better understood by a description of its operation, which is as follows: The cord having been threaded through the guides and eye of the arm 0, the end is inserted in the slots of the plates 0 c from below, between the blades or teeth of the cutter and holder a, and the end clamped and held by it, and the plate 0 being carried between them by the motion of the cutter and holder, the upper portion of the cord being forced within the grasp of the twister b by reason of the peculiar formation of the teeth of the cutter and holder 01. The twister b, which would also be revolved about one-half of a revolution at this time, will also clamp and hold the cord through the medium of a simple but effective devil-e, (not shown in the drawings,) and alterward, when the cord has been properly twisted, freed therefrom by the intervention of additional parts, all of which will be lelt for a full and clear description in a future application. ()n the descent of the arm 0 the second cord will be introduced into the slots and below the cutter and holder a as represented by broken lines in Fig. 2, and the upper portion around the bundle between the teeth of the twister b. The cutter and holder a, revolving, cuts off the cord and leaves the ends of the band within the grasp of the twister I), still retaining the end from which the band was severed within its grasp. As the twister I; revolves, twisting the ends of the band together, it so rotates as to untwist the strands of the separate ends of the band to a certain extent, while at the same time it unites them all into one strand or cord. This peculiar feature of the untwisting and uniting of the ends of the band by the twister b is an important element of my invention, for by practical tests I have found it to be the only sure way of joining the ends of the cord efi'ectively. After the twister b has made a suilicient number of turns the clamp arn1 (1 compresses the twisted and united cords firmly against the fixed arm (I, in the manner indicated in Fig. 4, near to the bundle, and then holds them for a suitable time. The twisted cords are now released by the twister b, and the tucker 7r tucks them under the band, and between it and the bundle, in the same way as that operation is performed with a straw band. As the tucker rotates back to its normal position the clamps d (1 release the bundle and it is forced from the machine, making way for the binding of another.

It will be observed, on an inspection of Figs. 2 and 3, that the extremity of the rotating shaft, to which the tucker is attached, does not extend quite over the center of the axle of the twister, and that the clamparm d abuts upon the end of said shaft, and that it will serve as a guide for the binding cord when being brought into contact with the cutter and twister by the binding-arm O. This arrangement, I have found by experiment, renders the work of the several parts more accurate.

\Vhat I claim as new, and desire to secure by Letters Patent, isi 1. In a device for uniting the ends ofa band, the combination of a rotary cutter and holder and twister with a clamping device for bold ing the cord, after being united by the twister, between the twisted ends and the gavel, and a rotary reciprocating tucker, whereby the said ends are tucked beneath the baud, substantially as shown and described.

2. A binder-arm for placing the band around the bundle, in combination with a; rotary twist er, a clamp independent of said arm, and located between the twister and the bundle, means for operating said clamp to hold the band after it has been united, and a rotary reciprocating tucker, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two witnesses.

ALBERT GOODYEAR.
